Short answer
The answer, before the reasoning
UK SRS S1 does not contain a fixed checklist of human-capital disclosures. An entity should identify how its business model depends on people - including critical skills, workforce capacity, safety, engagement, retention and relevant value-chain labour - and how weaknesses or improvements could affect revenue, costs, operations, assets, liabilities, cash flows, access to finance or cost of capital.
It then applies investor materiality, selects decision-useful metrics and explains governance, strategy, risk management and performance. UK statutory datasets can support the evidence, but their populations and definitions must be reconciled to the UK SRS reporting boundary.

Human capital is a business dependency before it is a metric set
UK SRS S1 asks for material information about sustainability-related risks and opportunities that could affect an entity's prospects. Human capital therefore starts with the way the business creates value, not with a standard employee dashboard. A bank may depend on cyber-security and credit-risk specialists; an engineering group on licensed professionals and site supervisors; a logistics operator on drivers, warehouse staff and safe contractor performance; and a technology company on product, data and sales talent.
Application guidance to UK SRS S1 explains that an entity depends on resources and relationships throughout its value chain and gives specialised workforce and human resources as examples. A shortage, deterioration or disruption in those resources can create risks, while investment, development and stronger relationships can create opportunities. The reporting task is to make that pathway visible to primary users.
1. What human capital can include under UK SRS S1
Not every area is material for every entity. Materiality depends on the nature or magnitude of the information, or both, in the context of the entity's circumstances. A relatively small group of safety-critical engineers can be material even when it represents a small percentage of headcount. Conversely, a widely reported workforce metric may be immaterial if it does not help primary users understand the entity's prospects.
In practice
| Area | Potential business dependency or exposure | Possible effect on prospects |
|---|---|---|
| Critical skills and leadership | Specialist capability, licences, succession, institutional knowledge and management capacity. | Delivery constraints, slower growth, control failure, project delay, weak innovation or higher remuneration costs. |
| Recruitment and labour market | Availability, location and cost of suitable workers; time needed to fill key roles. | Lost revenue, overtime and agency costs, inability to open capacity, or pressure on margins. |
| Retention and engagement | Turnover, voluntary exits, morale, trust, inclusion and employee relations. | Replacement cost, productivity loss, customer disruption, quality issues and execution risk. |
| Health, safety and wellbeing | Fatalities, injuries, dangerous occurrences, occupational health, fatigue and psychosocial risks. | Downtime, compensation, provisions, insurance, legal exposure, licence-to-operate and reputational effects. |
| Learning and workforce transition | Reskilling for technology, automation, climate transition, regulation or new products. | Ability to implement strategy, avoid stranded capability and capture new markets. |
| Pay, benefits and workforce affordability | Competitive pay, equal-pay risks, pension and benefit design, living-cost pressures. | Recruitment and retention effects, provisions, cash costs, disputes and reputation. |
| Labour relations and voice | Trade-union relations, consultation, grievances, speak-up systems and collective bargaining. | Industrial action, disruption, legal exposure, trust and early warning of operational risks. |
| Value-chain workers | Contractors, agency workers, outsourced services and labour conditions in suppliers. | Disruption, tender exclusion, customer loss, legal and reputational risk, remediation cost and supply insecurity. |
2. Build the dependency-to-financial-effect pathway
A useful human-capital assessment connects workforce evidence to the business model and financial consequences. It avoids both extremes: reporting only social impacts without explaining relevance to prospects, and reporting a generic financial risk without showing the workforce mechanism that creates it.
1. Identify the activity, product, service, facility or strategic programme that depends on people.
2. Describe the workforce dependency: capability, number, location, employment relationship, safety condition, culture or labour relationship.
3. Identify the vulnerability or opportunity, such as scarcity, turnover, injury exposure, poor succession, strong learning capability or improved workforce planning.
4. Identify the operational mechanism: delayed projects, lost shifts, reduced quality, lower utilisation, faster innovation, stronger customer retention or more resilient supply.
5. Translate the operational mechanism into current or anticipated effects on revenue, costs, assets, liabilities, cash flows, finance or cost of capital.
6. Assess time horizons, likelihood or uncertainty, and whether the information is material to primary users.
7. Determine the governance, strategy, risk-management and metric information needed to explain the conclusion.
Human-capital pathway under UK SRS S1
Workforce dependencies and impacts become decision-useful when the entity traces them through operational consequences to material effects on prospects and controlled disclosures.
3. Apply UK SRS materiality without importing another framework's conclusion
UK SRS S1 is investor-focused. Information is material if omitting, misstating or obscuring it could reasonably be expected to influence decisions of primary users of general purpose financial reports. Workforce impacts can be important evidence and can drive risks or opportunities, but impact significance under GRI or double materiality under ESRS does not automatically determine UK SRS materiality.
The entity should also test whether a workforce issue is material by nature even before a precise financial amount is available. A fatal accident, widespread labour-rights allegation, loss of a statutory licence population or industrial dispute at a critical facility may be decision-useful because of its character, concentration and potential consequences.
In practice
| Question | Evidence to consider | Decision record |
|---|---|---|
| Is the workforce dependency central to the business model or strategy? | Revenue concentration, critical roles, capacity plans, licences, succession, service commitments. | Dependency and affected strategic objective. |
| Could the issue affect prospects? | Operational disruption, cost trend, productivity, customer outcomes, provisions, capex, financing or reputation pathways. | Current and anticipated financial-effect pathway. |
| Is the information material by nature or magnitude? | Scale, concentration, sensitivity, uncertainty, severity, stakeholder and regulatory context. | Materiality rationale and threshold evidence. |
| Does aggregation obscure a material population? | Role, geography, site, contract type, gender, business unit, risk category and value-chain tier. | Required disaggregation and confidentiality safeguards. |
| Is a reported metric comparable and understandable? | Definitions, boundary, period, denominator, methodology, estimates, changes and external benchmarks. | Metric dictionary and change log. |
4. Map human capital to the four UK SRS content areas
Connectivity matters. A report is weak when strategy describes a talent shortage, the risk section describes only generic 'people risk', the metrics section presents total headcount and training hours, and the financial statements or management commentary show unexplained recruitment costs or restructuring provisions. The disclosures should describe the same underlying issue at appropriate levels of detail.
In practice
| Content area | Human-capital questions | Typical evidence |
|---|---|---|
| Governance | Who oversees workforce risks? How are safety, succession, culture, pay or value-chain labour escalated? What skills and information does the governing body receive? | Committee terms, board papers, dashboards, minutes, escalation criteria and challenge records. |
| Strategy | Which workforce dependencies affect the business model and strategy? What current and anticipated financial effects arise? What plans, trade-offs and resource allocations respond? | Workforce plan, strategic capability map, budget, restructuring or reskilling plan, financial analysis and scenario assumptions. |
| Risk management | How are workforce risks identified, assessed, prioritised and monitored? How are they integrated into enterprise risk management? | Risk taxonomy, registers, incident analysis, workforce heat maps, supplier due diligence, controls and remediation tracking. |
| Metrics and targets | Which metrics show exposure, performance and progress? How are methods, targets, baselines and changes controlled? | Metric dictionary, HRIS extracts, payroll and safety reconciliations, target approvals, calculations and review sign-off. |
5. Select industry-informed and entity-specific metrics
UK SRS S1 requires metrics that enable primary users to understand performance in relation to material sustainability-related risks and opportunities. When no dedicated UK SRS topic standard exists, the entity considers applicable UK SRS requirements and may refer to and consider SASB Standards. It may also consider CDSB material, other investor-focused standard-setter material, industry practice and peer information. Where useful and non-conflicting, GRI and ESRS may support the process. The entity discloses the sources of guidance it actually applied.
In practice
| Metric family | Illustrative metric | Decision-useful context and controls |
|---|---|---|
| Workforce composition | Headcount and full-time equivalent by critical population, geography or contract type. | Define employee, worker, contractor and agency populations; reconcile to HR and finance boundaries; avoid a total that obscures critical groups. |
| Recruitment | Vacancy rate, time to fill, offer acceptance or hard-to-fill roles. | Link to roles that constrain strategy; explain requisition definitions, ageing and treatment of frozen vacancies. |
| Retention | Voluntary turnover or regretted loss in critical populations. | Use a stable denominator and period; distinguish restructuring, retirement, involuntary exits and transfers where material. |
| Skills | Coverage of required certification, capability gap, learning completion or proficiency. | Training hours alone may not show capability; connect learning to required skills, assessments and deployment. |
| Safety | Fatalities, total recordable incidents, lost-time injuries, severity, near misses or contractor incidents. | Explain standard used, population, hours denominator, acquisitions and contractor coverage; separate RIDDOR from broader internal metrics. |
| Wellbeing and absence | Absence rate, occupational-health cases, fatigue indicators or employee assistance usage. | Protect privacy, explain data completeness and avoid unsupported causal conclusions about wellbeing programmes. |
| Engagement and voice | Survey score, participation, grievance themes, speak-up cases or resolution time. | Explain instrument, population, anonymity, material themes and why a score is linked to risk; a high response rate is not proof of positive culture. |
| Pay and equity | Pay gaps, living-wage coverage, remuneration distribution or benefit access. | State legal-entity and workforce population, methodology and differences from statutory gender pay gap reporting. |
| Value-chain labour | Supplier workforce risk coverage, due-diligence findings, remediation or worker-voice reach. | Distinguish supplier screening, audit activity, confirmed outcomes and effectiveness; explain tiers and risk-based scope. |
Gender pay gap reporting
UK gender pay gap reporting can provide useful evidence, but its legal boundary may not match the UK SRS reporting entity. Official guidance requires an employer with 250 or more employees on the relevant snapshot date to report for each separate legal entity in scope. UK SRS S1, by contrast, uses the same reporting entity as the related financial statements. A group should therefore retain the statutory calculations but reconcile legal-entity results, employee definitions, snapshot dates and overseas or acquired entities before using them in a group-level UK SRS disclosure.
RIDDOR and wider safety performance
RIDDOR captures defined reportable incidents, including deaths, specified injuries, certain occupational diseases and dangerous occurrences. It is not a complete measure of safety performance. The entity may need broader internal metrics such as total recordable cases, lost-time cases, severity, near misses, exposure hours and contractor incidents. The report should explain the relationship between statutory RIDDOR data and any wider methodology rather than using the terms interchangeably.
Modern slavery and value-chain labour
Section 54 of the Modern Slavery Act 2015 requires certain commercial organisations that carry on a business or part of a business in the UK, supply goods or services and have annual turnover of at least £36 million to produce an annual statement. That statement, supplier-risk work and due-diligence evidence can support UK SRS analysis of value-chain labour risks. However, legal applicability and statement completion do not by themselves establish UK SRS materiality, metric quality or effectiveness. The entity still needs to identify pathways to prospects, relevant scope, outcomes, limitations and financial consequences.
Privacy, sensitive information and small populations
Workforce reporting can involve health, trade-union, ethnicity, disability or other special-category data protected under UK data-protection law. The reporting team should use lawful, proportionate processing; minimise data; aggregate or suppress small populations where necessary; control access; and document the relationship between internal evidence and public disclosure. A material narrative can often be provided without publishing identifiable personal information.
In practice
| Dataset | Common boundary difference | Required reconciliation |
|---|---|---|
| Payroll | Paid employees by employing entity and pay cycle; may exclude contractors and unpaid leave. | Reconcile legal entities, periods, duplicates, leavers, international payrolls and FTE/headcount basis. |
| HR information system | May include inactive records, applicants, contingent workers or historical assignments. | Define active population, reporting date, transfer treatment and acquisition/disposal rules. |
| Safety system | May use sites, hours worked and incident classifications rather than financial entities. | Map sites and contractors to reporting entity; reconcile hours, incident standard and restatements. |
| Learning platform | Completions may not prove competence and may omit local systems. | Map courses to capabilities, remove duplicates, identify assessed proficiency and disclose coverage. |
| Supplier due diligence | Risk-based samples and tiers, not the whole value chain. | State coverage, risk basis, limitations, findings, remediation and outcome evidence. |
7. Include value-chain workers where the risk pathway requires it
The UK SRS value chain extends beyond employees of the consolidated group. Contractors may perform safety-critical work at the entity's sites; outsourced service providers may deliver customer-facing activity; recruitment agencies may affect labour standards; and suppliers may depend on migrant, temporary or low-paid workforces. These relationships can create operational, legal, market, reputational and financing consequences.
The entity does not need to collect every workforce datapoint from every supplier. A proportionate process starts with value-chain mapping and risk screening, then prioritises sectors, geographies, commodities, services, recruitment channels and contract types associated with material exposure. Metrics can be coverage-based or outcome-based, but the report must not present screening or audit activity as proof that adverse outcomes are absent.
1. Map workforce-dependent value-chain activities and identify the entity's leverage or operational dependence.
2. Screen for safety, labour, skills, recruitment and human-rights risk using sector, country and relationship evidence.
3. Connect priority risks to disruption, customer, tender, legal, remediation, insurance or financing pathways.
4. Define the data population and distinguish employees, non-employee workers, contractors and supplier workers.
5. Record estimation methods and data gaps where direct information is unavailable.
6. Track action, remediation and outcome evidence rather than reporting only policies and audit counts.
8. Hypothetical example: an engineering and field-services group
The reporting team does not conclude that total workforce turnover is the material issue. It identifies a concentrated skills and retention risk in a critical population, supported by vacancy ageing, project delay, agency cost and customer-delivery evidence. It also identifies contractor safety and labour-provider risk as separate value-chain pathways. Finance models the effect of delayed mobilisation and additional labour cost using ranges because project timing remains uncertain.
The example works because it identifies the material population, business dependency, method, boundary, operational consequence, financial pathway and limitation. It does not claim that turnover alone caused all project delay, and it does not mix employees, contractors and supplier workers in one denominator.
In practice
| Element | Illustrative decision | Evidence and control |
|---|---|---|
| Material risk | Loss and scarcity of high-voltage engineering capability could constrain project delivery over the short and medium term. | Critical-role register, turnover analysis, vacancies, utilisation, order book and project-delay review. |
| Strategy response | Apprenticeship expansion, retention actions, workforce planning, selective acquisitions and international mobility. | Approved plan, budget, capacity assumptions, milestone and governance papers. |
| Financial effect | Higher agency and recruitment cost, delayed revenue and possible margin pressure; ranges used because delivery timing is uncertain. | Finance model, assumptions, scenario ranges and reconciliation to planning data. |
| Metrics | Critical-role turnover, time to fill, certified-capability coverage, project delay attributable to skills, employee and contractor safety rates. | Controlled definitions, reconciled populations, hours and methodology change log. |
| Value-chain risk | Recruitment-fee and worker-treatment risk in labour providers could affect supply continuity, tenders and reputation. | Provider mapping, worker engagement, due diligence, remediation and escalation records. |
9. Evidence and internal controls
Responsibility should be split. HR, safety, procurement and operations own source processes; the reporting team owns the disclosure assembly; finance challenges financial pathways and reconciliations; legal or data-protection specialists review sensitive or statutory information; and governance bodies approve material conclusions and public claims.
In practice
| Control area | Minimum control | Evidence retained |
|---|---|---|
| Population and boundary | Approved definitions and mapping between financial entities, HR entities, sites, payrolls and contractor populations. | Boundary memo, entity/site map and reconciliation. |
| Metric methodology | Controlled formula, numerator, denominator, period, classification, estimates and restatement rules. | Data dictionary, methodology note and version history. |
| Source data | System extracts are complete, dated and access-controlled; manual files are approved. | Extract logs, access records, completeness checks and owner sign-off. |
| Reconciliation | Headcount, payroll, safety hours and material costs are reconciled to relevant finance or operational records. | Reconciliation workbook and resolved exceptions. |
| Judgement | Critical populations, materiality and financial pathways are challenged by HR, operations, risk and finance. | Decision paper, meeting record and approval. |
| Narrative claims | Statements about culture, effectiveness or improvement are supported by outcomes and balanced evidence. | Survey analysis, incident trends, actions, limitations and legal review. |
| Privacy | Public disclosure is aggregated and personal data access is restricted to legitimate purposes. | Privacy assessment, suppression rules and disclosure review. |
10. Emerging ISSB guidance: describe the status precisely
The ISSB has been researching human-capital disclosure to assess the necessity and feasibility of standard-setting. At its December 2025 meeting, the board received an update and was not asked to make decisions. At 2 August 2026, the official work-plan page identified the next milestone as deciding project direction. This is useful evidence that investor-focused human-capital guidance may develop, but it is not a final standard, an effective date or a UK requirement.
Entities should monitor the project and preserve a flexible data model, but they should not delay current UK SRS work. Material human-capital risks are already reportable through UK SRS S1. Future ISSB work may refine topics, metrics or disclosure architecture; any future use in UK regulation would also require the relevant UK adoption or rule-making process.
In practice
11. Common mistakes and corrections
| Mistake | Why it fails | Correction |
|---|---|---|
| Publishing a standard HR dashboard without a materiality pathway | Metrics may be familiar but do not explain the risks or opportunities affecting prospects. | Start from business dependencies and map each metric to a material decision. |
| Using total group turnover to describe a critical-skills problem | Aggregation can obscure a concentrated exposure in a small population. | Disaggregate by material role, geography or business unit and explain the basis. |
| Treating statutory gender pay gap data as the group UK SRS boundary | The statutory report is by separate legal entity and snapshot date, which may differ from consolidated reporting. | Reconcile populations and explain differences before reuse. |
| Calling RIDDOR the total injury rate | RIDDOR covers defined reportable events, not every incident or exposure hour. | Use precise terminology and reconcile it to the wider safety methodology. |
| Reporting training hours as evidence of capability | Completion does not prove competence, deployment or strategic readiness. | Connect learning to required skills, assessment and coverage. |
| Reporting policies and audits as proof of value-chain labour effectiveness | Activity evidence does not establish outcomes or absence of harm. | Report findings, worker evidence, remediation, limitations and outcome indicators. |
| Publishing sensitive small-population data | Detailed disclosure can identify individuals or create data-protection risk. | Aggregate, suppress or narrate the material point with appropriate safeguards. |
| Saying the ISSB human-capital standard is imminent or final | The project direction had not yet been decided at 2 August 2026. | Use dated, conditional project-status wording and maintain an update trigger. |

Questions
Questions people ask
Does UK SRS S1 require workforce disclosure?
UK SRS S1 does not contain a fixed checklist of human-capital disclosures. An entity should identify how its business model depends on people - including critical skills, workforce capacity, safety, engagement, retention and relevant value-chain labour - and how weaknesses or improvements could affect revenue, costs, operations, assets, liabilities, cash flows, access to finance or cost of capital. It then applies investor materiality, selects decision-useful metrics and explains governance, strategy, risk management and performance.
Which employee metrics should a company report under UK SRS S1?
UK SRS S1 does not contain a fixed checklist of human-capital disclosures.

It then applies investor materiality, selects decision-useful metrics and explains governance, strategy, risk management and performance.
Can gender pay gap data be reused for UK SRS?
UK gender pay gap reporting can provide useful evidence, but its legal boundary may not match the UK SRS reporting entity. Official guidance requires an employer with 250 or more employees on the relevant snapshot date to report for each separate legal entity in scope. UK SRS S1, by contrast, uses the same reporting entity as the related financial statements.
Is RIDDOR the same as a safety rate?
RIDDOR captures defined reportable incidents, including deaths, specified injuries, certain occupational diseases and dangerous occurrences. It is not a complete measure of safety performance.
Has the ISSB issued a human-capital standard?
At its December 2025 meeting, the board received an update and was not asked to make decisions. At 2 August 2026, the official work-plan page identified the next milestone as deciding project direction. This is useful evidence that investor-focused human-capital guidance may develop, but it is not a final standard, an effective date or a UK requirement.
